Question

A rectangle is inside a circle with a 5cm radius.

What is the area of the shaded region?
Use 3.14 for (pi).
Enter your answer in the box.

Answer 1

The area of the shaded region is 30.5 cm^2.

Explanation:

So, first you need to find the area of the circle and rectangle separately.

The diagram shows that the circle radius is 5 cm; use the formula pi*r^2 to solve for the area.

The area of this circle:

3.14*5^2

3.14*25

=78.5 cm

The area of this rectangle:

8 cm*6 cm = 48 cm

Now subtract the rectangle's area from the area of the circle.

78.5-48 = 30.5 cm
